Nephrocutaneous fistula is a very rare complication of renal surgery. It may be associated with renal tumors, nonfunctional kidneys, staghorn calculi, renal trauma or chronic urinary tract infections. Because of widely used imaging techniques an early detection of small renal tumors has modified the management of kidney cancer. Nephron sparing surgical resection remains the standard of care for T1 tumors less than 7 cm. For patients who are not amenable for surgery, microwave thermal ablation (MWA) is gradually becoming a preferred treatment modality. In this article we present a rare complication after microwave thermal ablation for small tumor. For a 75-year-old patient a CT was performed: Two tumors were identified. One tumor was 16 mm in diameter, the second one was 37 × 28 × 44 mm. Biopsy was performed before MWA. Papillary adenocarcinoma G2, I type was found. Microwave thermal ablation of right renal tumor was performed for 15 minutes 35W. The patient was released. Two weeks after an MWA urine started leaking from the needle insertion area. It was decided to insert a ureteral stent, but the stenting was complicated. After 3 month radical nephrectomy was performed. A histological examination was performed no residual tumor was found. other serious comorbidities. However, the elderly, who are the main group of people diagnosed with this type of cancer, usually have multiple comorbidities. They have much more risk factors for perioperative and postoperative complications. Major surgeries requiting general anesthesia should be avoided for older patients and those with high-risk comorbidities, including severe cardiovascular and pulmonary diseases. For patients who are not amenable for surgery because of comorbidities, advanced age, who already have precarious kidney function, who have solitary kidney or prefer less invasive treatment option, the percutaneous approach is feasible. There are three main percutaneous image-guided ablative therapies in use: Radiofrequency ablation, cryoablation, and microwave ablation. In each case, one or more needles are inserted into the tumor and energy (heat or freezing) is used to destroy the tumor. Ablation therapies are associated with less treatment related morbidity and mortality than resection. The different techniques vary in terms of time needed for treatment, ability to monitor the process, and other patient and tumor dependent factors. Radiofrequency ablation and cryoablation may present limitations in terms of efficacy for tumor greater than 3-4 cm. Microwave thermal ablation may be beneficial in this setting. During MWA consistent higher intratumoral temperatures are provided than during other ablation procedures. Because of lack of studies with midto long-term follow up there’s insufficiency of data CAsE REpoRt
